Dolphin Finds A Home

A growing appreciation of the benefits of podded electric propulsion is widening the concept's market reach, although business for such systems has remained concentrated among just a handful of suppliers. The recent deal for the Dolphin system, while denoting the commercial breakthrough for the alliance between STN Atlas Marine Electronics of Germany and John Crane-Lips of the UK, also expresses the market's receptivity to a further option and additional player.

Two Dolphin propulsors have been ordered for Radisson Seven Seas' 48,000-gt diesel-electric cruise liner under construction at Mariotti's premises in Genoa harbor.

STN Atlas Marine's prowess in electrical engineering melded with John Crane-Lips' Dutch-honed skills in propellers, thrusters and hydrodynamics has resulted in a pod line covering units powers between 3-MW and more than 19-MW. The prestigious, milestone cruise ship application calls for a pair of outboard, podded drives delivering 7,000-kW apiece at 170 rpm.

Radisson Seven Seas earlier demonstrated its belief in the design and oper- ating merits of podded propulsors through its selection of two 8.5-MW Mermaid units for its similar-capacity newbuild Seven Seas Mariner, now approaching completion at Chantiers de l'Atlantique.
